As very clearly disclosed, 1 and the strap 27 extends transversely of the cart in a normal position.

body and is situated closer to its rear than to its front so that normally the front portion of said cart body will rest upon the horizontal portions 28 of the supporting members (although this need not be the case). said portions 23 being offset inwardly, as indicated at 30, at points adjacent and forwardly of the pivots for the cart body to lie well within the confines of the base of said body, as will be understood.

The cart body has sides 31 and a tail gate 32 pivoted to the upper, rearward corners of the sides as at 83. Links 34 pivoted to the vertical portions 22 of the supporting members, adjacent the upper ends of said vertical portions, as at 35, and to the edges of the tail gate as at 36, hold the gate closed so long as the cart body rests upon the horizontai portions 23, as it is shown in Fig. 1. But when the cart body is swung on its pivot from the position of Fig. 1 to the position of Fig. 2, its rearward ends swings toward the pivotal points 35 to cause the links 34 to swing the toll gate on its pivots 33 to open position.

Mechanism is provided for operating the cart body from its normal position (as in Fig. 1) to its dumping position (as in Fig. 2), and vice versa, the mechanism including an arrangement for locking said cart body Of this mechanism, 87 represents a Z-shaped control lever including a hand piece 38 of any ordinary or preferred design, a shaft 39 desirably at right-angles to the hand piece and mounted in spaced apart cars 40 of a two-part bracket 41 secured as at 42 to the bottom face of the seat 10 adjacent its forward end, andaan arm. 43 preferably at right-angles to the shaft 39. The arm 43 is pivoted in some convenient manner to the forward end of a connecting bar 44 having its rearward end pivoted as at 45 to a tension member 46 secured to the bottom face of the base of the cart body. As disclosed, this tension member-is a single piece of metal having divergent legs extending longitudinally of the toy and secured centrally of the cart body as at 4'7, each leg terminating in a web 48 common to both legs and having an opening 49 freely and rotatably receiving a hook portion of the connecting bar 44, the bar being adapted to have pivotal movement in the web, and the web being designed to preclude accidental removal of the hook portion of the bar. See Fig. 4.

The manner of manipulating the cart body'will be evident from Figs. 1 and 2. By swinging the hand piece from either of its positions of Fig. 1 to its position'of Fig. 2, the control lever moves the connecting bar forwardly to cause the cart body, through its tension member, to rotate upon its pivots 29,'thus tilting the cart body to dumping position, the tail gate functioning in the manner already set forth. By returning the hand piece from its position of Fig. 2 to either of its positions of Fig. 1, the cart body is returned to normal position.

'1 he ears 40 of the two-part bracket mount the shaft 89 of the Z-shaped control lever at a slight distance from the bottom face of the toy seat, and when the control lever has been moved from its position of Fig. 2 to its dotted line position of Fig. 1, the cart body is resting upon the horizontal portions 23 of the supporting members 18. In Fig. 1 the dotted lines show the arm 43 of the control lever and the connecting bar in alignment. Evidently, movement of the control lever from its dotted line position in Fig. 1 toward its full line position in said figure throws the connecting bar beyond the dead center position of the control lever. The arrangement is such that the movement of the control lever from a position in advance of the dotted line position as shown to a position beyond said dotted line position (toward the full line position) is against the natural resiliency of the tension member, and when the control lever has passed its dead eenter position, it is carried to the full line position in Fig. 1, directly against the bottom face of the toy seat. Clearly, the cart body is thus locked in normal position. Any force exerted to dump it, except by manipulation of the control lever, only exerts pressure against the botom face of the seat.

The two-part bracket as fully described is essential to the assembly with the Z-shaped lever of efficient and practical means for mounting said control lever upon the toy seat.

Having thus fully described the invention, what 1 claim as new and desire to secure by Letters Patent is:

1. in a dump cart of the character described, a frame, a cart body pivotally mounted thereon, a tail gate pivoted to said cart body, a link pivoted to the frame and to the tail gate, means consisting of a tensicn member on said body, a control lever, a connecting bar between the control lever and tension member for swinging the cart body on its pivot to tilt. said body and thus swing the tail gate on its pivot away from the cart body, and means consisting of said connecting bar when moved against the resiliency of said tension member beyond a dead center position of said control lever and a fixed part upon said dump cart limiting movement of said connecting bar be yond said dead center position for locking the cart body in normal, untilted position.
